Creep under irradiation of annealed 316 steel was simulated in a high voltage electron microscope at 350/sup 0/C and 450/sup 0/C, to observe in situ the evolution of the microstructure as a function of time. Thermal creep occurs through heterogeneous planar glide. The various stages of creep under irradiation correspond respectively to the nucleation and growth of an anisotropic population of Frank loops, their subsequent unfaulting and the reaction of the perfect loops leading to a Corduroy contrast. During nucleation and unfaulting the applied stress favours one or a few Burgers vectors out of all those possible. These observations are compared to the various models explaining this phenomenon.
